To all 'fw/tom tf/may concern.' a y lle iii known that L @sca- R Znizn, -a vsubject of the Emperor .of Austria, residing Aat Cleveland, in the county'ff Cuyahoga and State ot' Ohioyhave invented-a certain new anduseful lmprimtement in Grease-Cups, of which the following isa full, clear, ander;- act description, reference being had to the accompanying drawings.

detent device in vielvdable en-gagement'with ythe cap. Y

The invention is concerned particularly with `the construction and arrangement of the described parts ifor ,producing an ineX-.

pensve,'durable and efficient 1, grease cup, ivh-iclr particularlyneat; pleasing and attractive in appearance.

in the drawing, Figure 1 isa side elevation of a grease cup embodyingimy invention; 2 is a vertical central section thereof; Fig, is a 'plan view, and Fig. 4 is a plan ot' the detent device showing a portion 'of the operating spring therefor within it and showing the shank of the cup in section. l

Assliown in the drawing, l represents the base oi the cup, which may conveniently be made ot two connected stampings. One of these is a -tubulai` stem or' shank member having a hexagonal exterior 2, va'reduced externalb; threaded nipple 3 at the lower end thereof, an internal bore 4f preferably 'enlrflrged at its upper portion and upper andlower rabbets 6 and l' near itsupper ond. The other stamping is the dislrilike head 8 which has a beveled centralopening oi" proper size to enable it to seat in the upper rabbet 7. hen soseated it is rigidly secured to the shank lmember outwardly upsetting the edge ofv .the latter into the bevel-space or upon the upwardlypresented ladjacent surface of the head. `The head 8 has a down-turned cylindrical lla-nge 9 which is externally threaded.

10 indicates the cap, which has a cylindrical ywall internally ,threaded `to screw onto the threads ofx the ange 9. The cap is shown as provided with nurling 1l .and ya wing 12, :tor facilitating the rotation thereol' which parts mayV be employed or not, as

desired 'It the wing is employed, it is'conrenient to make fit by stamping the head portion ofthe cap into the form shown in Y Figs. 1 QandQ.

2() indicates a detent device preferably 'formed of two nesting cups 2l and which slidably surround the 'shank 2,' the innerypart for cup preferably having edge .projections for engaging notches 13 in the lower edge ofthe cap and the outer .cup 21 4ef(tending above the cup Q" to cover'and'conceal ,the engaging edges ,ol the cap and cup'22. The central opening through one, ypreferably the upper, of the nesting cups 21 and22, is made angular, corresponding tothe shank 2 to prevent ,the detent device'from rotating on the shank. but permitting vit to `slide ,thereon. An yannular lrecess is provided 'between they two members 21, 22, preferably by depressing` a portion ,of the bottoln of the member 21. Entrance is provided'to this recess by means of an opening 'Q8 in the bottom of the member 29 adjacent'to 4its central opening.

S30 indicates the spring which draws the datent device toward' the cap. and holdsthe 'irojectious 23 in engagement with the'walls ot the notches 13. y"This spring is housed or concealed within the cups 21, 22, and is preferably an open-coil tension helix, so

tormed that each coil tendsl'o more past the adpicent coil in the directionof thefre- Vtraction. l may accomplish this by twisting' or distorting ythe if'arious coils, or, Mby

taking' an open-coil spring and turning it i n l wrong-side-out to give an added .twlstvto thecoils and 'increase' thetension effect. The

spring is anchored at itslower ,ends'to' the detent vdevice/by h'aving'its lowermost .coil

turned through the opening r28 into the annular recess between Jdie membersl, 22, as shown'at 31 in Figs. 2 ,and 4. The Coil is anchored at its upper end to the cup -"by having its ul'ipermost coil occupying the annular groove provided by the rabb'etbl in the upper Ipart of theY shank 2 andthe under acenof the head 8. The tendency of this spring'to retract maintains the rejections '23 in constant engagement 'wlththe lower edge of the cap, so that, asthe cap is turned down to feed ythe grease,'tl1e projections periodicallyenter the notches and deioe abil the Spiiiig.
